BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to beverage containers, and more particularly, to a portable beverage container.

2. Description of the Related Art

Modern-day lifestyles are increasingly mobile, especially in urban communities. Individuals are often on the go regardless of financial status, marital status, sex, and parental status. Since such individuals are typically stretched for time, they tend to accomplish certain tasks while they are in route between activities, errands and avocations and/or while they are attending to their activities, errands and/or avocations. This trend has led to products designed to suit such lifestyles.

One example of a category of tasks that contemporary individuals accomplish while in route or during their activities is mobile communications. Another category is replenishments and consumables, for example, drinking beverages and eating foods in portable containers in the car, at work, during sports activities or other activities. In particular, beverages, such as coffee, tea and sports drinks are often consumed on the go. For example, often individuals either buy or make their beverages to take with them so they can consume their beverage wherever, for example, in a vehicle, in a meeting, during sports activities, or any other place where traditional beverage containers such as ceramic mugs or glass cups are not suitable.

Portable beverage containers are typically made from material that is light and resilient to impact because portable beverage containers often face demanding conditions such as being placed on slippery surfaces, dropped, and/or aggressively manipulated, for example while the user is driving. Such material may include plastics, rubbers, silicone, or other material that is light and not easily breakable. However, such material typically adversely affect a taste of the beverage and/or take away from a drinking sensation typically associated with non-portable beverage containers such as cups and mugs made from ceramic, bone china, stones, and/or glass.

Accordingly, there is a need for a beverage container that is portable and enhances the user's drinking sensation while being adapted to withstand demanding conditions of mobile use of the container.

BRIEF SUMMARY OF THE INVENTION

According to one embodiment, a portable beverage container from which a user can consume a beverage, comprises a base having a seat adapted to support the beverage container, the base being fabricated from a first material comprising a metal, rubber, plastic, silicone, foam, and/or wood, to promote at least one of portability and durability of the portable beverage container, and a lip which the user contacts when consuming the beverage, the lip sealingly and rigidly coupled to the base and fabricated from a second material comprising ceramic, bone china, stone, and/or glass, to enhance a drinking sensation of the user.

According to an aspect of the foregoing embodiment, the portable beverage container may further comprise a coupling ring positioned between the base and the lip, the coupling ring rigidly attaching the body to the lip, and being adapted to prevent liquid from escaping therebetween.

According to another aspect of the above embodiment, the portable beverage container may further comprise a handle having a core at least partially encased in an over-mold, such as a silicone over-mold.

FIG. 1 illustrates one embodiment of the present invention in which a portable beverage container 100 comprises a drinking portion having a lip 102 which a user contacts when consuming a beverage. The portable beverage container 100 may further comprise a base portion 108 that may form at least a dominant portion of a body 106 of the portable beverage container 100. The base portion 108 can be sealingly and rigidly attached and/or coupled to the lip 102, for example through a coupling device 110. The coupling device 110 can for example comprise a fitting or a coupling ring having protrusions 117, 119 that lock into complementary recesses in the lip and base portions 102, 108, or vice versa. Additionally, or alternatively, the coupling device 110 can incorporate liquid-tight first and second seals 121, 123, or can be silicone over-molded onto the lip 102 and/or the base portion 108. Additionally, or alternatively, the lip and base portions 102, 108 can be attached via adhesives and/or bonding material, or by any other suitable means that can sealingly and rigidly attach and/or couple the lip 102 to the base portion 108 and withstand temperatures and/or conditions typically encountered by portable beverage containers.

The user's lips and tongue typically contact the lip 102 and a terminating surface 104 of the lip 102 of the portable beverage container 100. Therefore, a material of the lip 102 can affect a taste of the beverage or a drinking sensation of the user. The lip of conventional portable beverage containers incorporate material such as plastics or foam, which adversely affect the taste of the beverage and take away from the drinking sensation. However, since the lip 102 and the base portion 108 of the illustrated embodiment of FIG. 1 are distinct, they can be fabricated from distinct materials, materials that best suit the lip and base portion 102, 108 of the portable beverage container 100, respectively. For example, the lip 102 can be fabricated from a first material adapted to enhance the drinking sensation of the user, such as ceramic, bone china, different types of stones, and/or glass or any other material typically known to enhance the drinking sensation of the user. Furthermore, the base portion 108 can be fabricated from a material that promotes portability and/or durability of the beverage container 100. For example, the base portion 108 can be fabricated from material comprising plastics, natural and/or synthetic rubbers, silicone, composites, metals, foams, woods and/or any other material that may include qualities promoting portability and/or durability, such as being light, non-slip, non-stick, resilient, and/or durable.

In some embodiments, the base portion 108 may comprise more of the body 106 than the lip 102, the lip 102 comprising a minimum size to conform to lips of the user to create the drinking sensation typically associated with material such as ceramic, bone china, stones, and/or glass. The beverage container 100 can be a cup, a mug, a sport bottle, or any other type of beverage container used in different applications. Furthermore, the beverage container 100 can be of any size, such as small, medium, large, extra large and/or short, tall, grande, and/or any other size. At least one of the lip 102 and base portion 108 can form a body 106 of the beverage container 100, the body 106 having a cylindrical shape including parallel and/or non-parallel sides.
